INSULATOR.

Application filed lune 24, 1922. Serial No. 570,736.

This inventionrelates to insulators particularly adapted for attaching wires to buildings or other supports, and has for its object to provide an inexpensive device having the requisite strength and insulating properties and being easily attached to the support and the wires without material injury thereto.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the accompanying drawings, Fig. 1 is a side elevation of an insulator embodying the invention;

Fig. 2 is a transverse sectional view of the insulator taken on the line 22 of Fig. 1; and

Fig. 3 is a longitudinal sectional view of a modified form of insulator.

In these drawings 10 indicates the body of and forms a metal core for the insulator body. The insulator body may be formed of any suitable insulating material, such as porcelain or a hardened plastic. The openin" 15 formed in. the body permits the wire being passed through the insulator at different angles of approach without requiring a The insulator body may also have a notch the screw and then inserting a rod, a screwdr ver or other suitable implement n theopening and turning this implement. The broad fiat base gives ri 'dity to the device and avoids bending of t e screw shank.

The invention provides an inexpensive insulator Well adapted for the purpose intended and not liable to injury.

' What we claim as our invention is:

1. An insulator, comprisinga body of insulating material having a transverse wirereceiving aperture and a support-engaging base, there being a slot in said insulator body including a curved portion about said aperture adjacent the outer end of said insulator body, and an attaching member including a single threaded wood screw shank projectin from the base of said insulator body and having a hooked end disposed and permanently secured Within the curved portion of said slot to reenforce said aperture and to retain said attaching member in said insulator body against relative rotation for turning the threaded shank of said attach-- ing member into a support by the rotation,

of said insulator body.

2. An insulator, comprising an insulator body having a transverse wire-receiving aperture and a support-engaging base, there being a slot in said insulator body including a curved portion about said aperture, and

sharp bend in the wire with a consequent" an attaching member having a sin le thread- 19 communicating with a bore '18 may be provided. In either of these cases the slots may be filled with suitable cement 20 after the loop ended attaching member has been put in place.

ed screw shank projecting from the base of said insulator body and having a loopedcnd portion disposed and permanently secured .within the curved portion of said slotto reenforee said aperture and to retain said at-' taching member in said insulator body against relative rotation for turning the threaded shank of said attaching member into a support by the rotation of said insulator bod In testimony whereof, we afiix our signatures.
